What type of hydro-electric plant generates energy during peak demand?

A pumped storage plant is designed specifically to generate energy during peak demand periods. It operates by using excess energy during low-demand times to pump water from a lower reservoir to an upper reservoir. When energy demand increases, water is released back down to the lower reservoir through turbines, generating electricity in the process. This ability to ramp up power generation quickly in response to peak demand makes pumped storage plants an essential component of energy management in electrical grids.

Run-of-the-river plants and storage hydroelectric plants typically rely on constant water flow and are not primarily configured to handle sudden increases in demand. Base load plants provide a continuous supply of energy but may not be able to quickly adapt to sudden changes in demand. Therefore, the pumped storage plant stands out as the most effective solution for generating energy during peak demand moments.
